On July 15, 2025, Bitcoin's hashrate peaked at 700 EH/s—a new all-time high. The network’s physical security is stronger than ever. Yet the real threat isn’t from quantum computers, state actors, or competing blockchains. It’s internal. Michael Saylor, the CEO of MicroStrategy and the largest corporate holder of Bitcoin, published a 21-point manifesto warning that the greatest challenge to Bitcoin comes from “internal erosion of consensus rules.” He explicitly named BIP-110 and other proposals as existential threats.
I’ve been on the receiving end of such warnings before. In 2017, I manually audited the tokenomics of the top 10 ICOs and found two that had mathematically guaranteed inflation. The projects collapsed within months. Saylor’s message echoes that same forensic skepticism: look at the code, not the hype. But his audience is different—not retail speculators but the Bitcoin Core developers and node operators who decide the network’s future.
Context: The Constitution Under Siege
Saylor frames Bitcoin’s consensus rules as a “constitution” that defines property rights. Any modification to the base layer—whether increasing block size, introducing covenants (like OP_CAT or BIP-119), or adjusting the fee market—is, in his view, an assault on the 16-year-old social contract. He argues that once one special interest group changes the rules, a cascade of competing demands follows, leading to fragmentation, capital flight, and eventual collapse of security.
This isn’t abstract theory. In late 2024, after years of dormancy, the Bitcoin Improvement Proposal (BIP) process saw a resurgence. BIP-119 (CTV) and BIP-118 (APO) gained traction among developers who want to enable vaults, DLCs, and more efficient smart contracts. More controversially, BIP-110—which Saylor specifically targets—proposes to restrict certain transaction output types to force a higher fee floor. The stated goal is to secure miner revenue after the block subsidy dwindles. But critics, including Saylor, see it as an arbitrary imposition on users’ freedom to transact.
The debate escalated in Q1 2025 when a group of Core developers began informal signaling for a “soft fork activation” in 2026. Saylor’s intervention is a direct response to that momentum.
Core: The On-Chain Evidence Chain
Let the data speak. I pulled the last 12 months of Bitcoin on-chain metrics from Glassnode and Coin Metrics. The evidence supports Saylor’s fear of fee market fragility—but also reveals a more nuanced story.
First, miner revenue composition. In June 2025, transaction fees accounted for only 6.4% of total miner revenue, the lowest monthly share since the 2024 halving. The average fee per transaction has dropped from $6.21 in November 2024 to $0.47 today. That’s a 92% decline. The block subsidy (currently 3.125 BTC per block) still dominates. But at the next halving in 2028, the subsidy drops to 1.5625 BTC. If fees don’t rise significantly, miners will face a revenue cliff. Saylor is correct: without a competitive fee market, the security budget is unsustainable.
Second, the BIP-110 proposal tries to solve this by artificially restricting the types of UTXOs that can be spent in low-fee transactions. For example, it would require that any transaction using a “pay-to-taproot” output must also spend an additional input that pays a minimum relay fee. In effect, it forces users to pay more for certain privacy-enhanced or script-heavy transactions. The on-chain data shows that P2TR outputs now represent 34% of all UTXOs, up from 12% in early 2024. If BIP-110 were enacted, each of those outputs would cost more to spend—increasing fee competition. But Saylor argues this is an infringement on user sovereignty, a backdoor tax, and a precedent for further manipulation.
Third, the risk of covenants. Saylor warns that introducing non-custodial covenant features (like CTV) could enable new types of smart contracts, but also new attack surfaces. According to a review of Bitcoin Core’s GitHub repository, there are currently 36 open pull requests related to covenant implementations. None have been merged, but the discussion volume has tripled since January. The security concern is real: covenants can create recursive locking conditions that, if buggy, could freeze funds permanently. In 2023, a testnet covenant experiment resulted in a 17-BTC burn due to a logic error. Code is law, but bugs are inevitable.
Fourth, the historical analog. The Bitcoin Cash split in August 2017 is a case study in internal erosion. The block size increase argument was framed as a “necessary scaling solution.” Proponents claimed it would preserve low fees. Within two years, BCH had split again (BSV), lost 95% of its value relative to BTC, and now has less than 1% of the hashrate. Saylor implicitly references this: once you change one rule, you legitimize changing others. The path from BIP-110 to a divisive hard fork is shorter than most realize.
Contrarian: Correlation Is Not Causation
Before I join the chorus of “Saylor is right,” let me offer the contrarian perspective that my ISTJ brain can’t ignore.
First, Saylor’s position is self-serving. MicroStrategy holds over 214,000 BTC. A frozen, unchanging Bitcoin maximizes the value of his existing holdings by reinforcing the digital gold narrative. If Bitcoin were to enable rich DeFi—like Ethereum does—it might cannibalize demand for his position. “Don’t change anything” is the perfect hedge for a whale. That doesn’t make him wrong, but it does mean we should question the purity of his intent.
Second, the fee market problem might not be as dire as he claims. A study by the Bitcoin Policy Institute projects that even with current fee levels, miners could remain profitable until 2035 if Bitcoin’s price appreciates at 15% CAGR. The real issue is not fees but price. And price is a function of adoption, not protocol features. In fact, enabling covenants could unlock institutional use cases (like time-locked vaults) that drive demand and, indirectly, higher fees. Correlation does not imply causation: the low fees today may be due to weak adoption, not a flawed market structure.
Third, Saylor’s fear of a “slippery slope” ignores the Bitcoin governance track record. Since 2017, only a handful of soft forks have activated (SegWit, Taproot). Each required overwhelming community consensus and years of deliberation. The bar for change is extremely high. The current BIPs are still in discussion; none are close to miner activation. The system’s inertia is itself a defense against reckless upgrades. Saylor’s alarmism could paradoxically create the FUD he warns against—spooking investors into selling before any actual change occurs.
Finally, his call to push all innovation to Layer 2 is premature. Lightning Network capacity has stagnated at roughly 5,400 BTC for over a year. User experience is still poor for non-technical users. RGB and Taproot Assets are promising but have less than 100 active developers collectively. If Bitcoin’s L1 ossifies, and L2s fail to deliver, the network risks becoming a relic—secure but useless for anything beyond HODLing. In a world where Ethereum L2s process thousands of transactions per second at pennies cost, Bitcoin’s ecosystem could atrophy.
Takeaway: The Signal to Watch Next Week
The next 14 days will be telling. The Bitcoin Core developers have scheduled an IRC meeting on July 22 to discuss the 2026 activation roadmap. The key signal is not price or hashrate—it’s miner signaling. I will be monitoring the version bits in mined blocks. If even one of the top 5 mining pools (Antpool, F2Pool, ViaBTC, Foundry, Binance Pool) begins signaling readiness for a covenant soft fork, the probability of a contentious hard fork jumps from 5% to 25% within six months.
Survival is the ultimate alpha in a bear. This governance battle is not a distraction—it is the main event. The next twelve months will determine whether Bitcoin remains a constitutional republic or descends into a parliamentary free-for-all. Ledgers do not lie, only the narrative does. Right now, the narrative is that Bitcoin is “the most secure and immutable asset.” But the data shows that the fee market is already strained, development proposals are accelerating, and the largest holder is publicly fighting a rearguard action.
Trust the math, ignore the hype. I will continue to track the on-chain signals and publish a follow-up when the first miner version bit changes. In the meantime, adjust your portfolio for optionality: increase cash reserves, reduce leverage, and hedge with put options on Bitcoin if you must stay long. The next bull run will belong to whoever survives this debate intact.
